of KBDIO_DEBUG which may be defined in the kernel config (as it is in NOTES). This kind of bug is a _really_ horribly thing as we end up with one bit of code thinking a particular structure is 136 bytes and another that it is only 112 bytes. Ideally all places would remember to #include the right "opt_foo.h" file, but I think in practice file containing the variable sized struct should #include it explicitly as a precaution.
